Figure 9. APT analyses of commercially pure Ti (CP Ti) and Ti6246 alloy. (A and B) are the atom maps and the corresponding concentration profiles of CP Ti and Ti6246, respectively, using conventional FIB specimen preparation at room temperature. (C and D) are the counterparts using cryo-PFIB, which show the low extent of hydrogen uptake from the specimen preparation processes. Scale bars are 20 nm.
